When attempting to update one $arch of a package that has a multilib version installed, dnf gives a misleading error. For example, I have multilib versions of libX11 installed. While attempting to update from rdieter's copr for a QA test, I only had the x86_64 copr enabled. dnf reported "Error: cannot install both libX11-1.6.3-1.fc22.1.x86_64 and libX11-1.6.3-1.fc22.x86_64" which gave zero indication of the actual problem. Using yum-deprecated, I was able to discover the root problem: Protected multilib versions: libX11-1.6.3-1.fc22.1.x86_64 != libX11-1.6.3-1.fc22.i686 Yum displayed the actual error, that only one $arch of a multilib installed package was being updated and both arches needed to be in sync. Once the i686 copr was enabled, dnf proceeded normally. dnf should report that the problem is a multilib problem, not just that two x86_64 versions can't be installed at the same time.
Thanks for the report.
